enable_kernel_vsx() function was commented since anything was using
it. However, vmx-crypto driver uses VSX instructions which are
only available if VSX is enable. Otherwise it rises an exception oops.
This patch uncomment enable_kernel_vsx() routine and makes it available.

This patch disables the rfc4106 test while the conversion to the
new seqiv calling convention takes place. It also converts the
rfc4106 test vectors to the new format.

This patch replaces the seqniv generator with seqiv when the
underlying algorithm understands the new calling convention.
This not only makes more sense as now seqiv is solely responsible
for IV generation rather than also determining how the IV is going
to be used, it also allows for optimisations in the underlying
implementation. For example, the space for the IV could be used
to add padding for authentication.
This patch also removes the unnecessary copying of IV to dst
during seqiv decryption as the IV is part of the AD and not cipher
text.

This patch fixes a bug where we were incorrectly including the
IV in the AD during encryption. The IV must remain in the plain
text for it to be encrypted.
During decryption there is no need to copy the IV to dst because
it's now part of the AD.
This patch removes an unncessary check on authsize which would be
performed by the underlying decrypt call.
Finally this patch makes use of the type-safe init/exit functions.

This patch adds a type-safe function for freeing AEAD instances
to struct aead_instance. This replaces the existing free function
in struct crypto_template which does not know the type of the
instance that it's freeing.

Currently the task of freeing an instance is given to the crypto
template. However, it has no type information on the instance so
we have to resort to checking type information at runtime.
This patch introduces a free function to crypto_type that will be
used to free an instance. This can then be used to free an instance
in a type-safe manner.

Algo self tests are failing for CTR mode with omap-aes driver,
giving the following error:

[ 150.061262] alg: skcipher: encryption failed on test 5 for ctr-aes-omap: ret=22
This is because the input length is not aligned with AES_BLOCK_SIZE.
Adding support for omap-aes driver for inputs with length not aligned
with AES_BLOCK_SIZE.
